Use the GET-RECIP-REC, GET-RECIP-REC-C20, or GET-X400-RECIP UOW to
determine whether the originator requested delivery notification for a package.
Disclosure of Other
Recipients (P1)
This feature allows you to restrict disclosure of recipient names to other recipients;
recipients cannot retrieve any recipient name other than their own.
You can specify disclosure for individual messages. The CCITT standards specify
restriction of disclosure by default, but in order to preserve TRANSFER functionality
for programs that do not use X400, the TRANSFER delivery system does not restrict
disclosure unless you explicitly request restriction.
Data Structure
The recipient disclosure flag resides in the item descriptor.
Access
To restrict disclosure as specified by X400, use the ALTER-ITEM-DES-C20 UOW. Set
the DONT-DISCLOSE-RECIPS field in the DELIV-CONTROL-FLAGS portion of the
item descriptor.
For incoming messages, the GET-RECIP-REC, GET-RECIP-REC-C20, and
GET-X400-RECIP UOWs enforce disclosure for recipient type 300. The TRANSFER
delivery system does not restrict access to names that are stored in an item data
record—for example, you can use any GET-ITEM-REC UOW to retrieve names in data
records of record type 340.
Expiry Date
Indication (P2)
Expiry date indication allows you to specify an expiration date for a package.
Data Structure
The gateway maps the TRANSFER package expiration date into the expiry date
indication. Expiration date resides in the EXPIRATION-DATE field in the item
descriptor.
Access
Use any ALTER-ITEM UOW to set a package's expiration date.
Use any GET-ITEM UOW to retrieve the expiration date.
